python - Python TKInter破坏不起作用

Question

我正在尝试关闭 TKInter 窗口self.win.destroy。

bind将事件发送到按钮时会引发以下错误：

...
Can't invoke "bind" command: application has been destroyed
During handling the above exception, another exception occured:
...
Can't invoke "destroy" command: application has been destroyed

如何将“关闭窗口”命令绑定到按钮？

Answer 1

做这个：

button['command'] = root_window.destroy # give it the function
# when the button is pressed the call () is done

不要这样做：

button.bind('<Button-1>', root_window.destroy()) # () makes the call

因为

root_window.destroy()

button.bind在调用之前销毁窗口。

这也是错误的：但不会破坏根窗口：

button.bind('<Button-1>', root_window.destroy)

因为

• 无法用键盘触发按钮
• root_window.destroy(event)被调用但root.destroy()只接受一个参数。

这也有效：

button.bind('<Button-1>', lambda event: root_window.destroy())
